We normally think of monkeys in tropical surroundings, but these Japanese macaques, or snow monkeys, live in the Nagano mountains of Japan where temperatures hit well below freezing in winter. Highly sociable in their behaviour, they are the only monkeys to live in such cold temperatures. Their thick furry coats may help to keep them warm but they have found a more entertaining way to keep out the wintry chill : take a relaxing bath in the natural hot sources of the mountains. / Singes des neiges ( japanese maquaques ou Macaca fuscata) les singes les plus nordiques du monde, prenant un bain chaud dans les onsen naturels des Alpes japonaises, parc de Jigokudani, Honshu, Japon
